DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERREDEMBODIMENTS

Turning now to FIGS. 1-7, an inner wall system 10 for a cargo containeris provided. The system 10 may be used for a mobile cargo container,such as a cargo compartment 18 of a truck (FIG. 1), a railroad car, aboat, an aircraft, or the like. While the system 10 is explained anddepicted specifically with reference to a cargo compartment of a truck,one of ordinary skill in the art with reference to the subjectspecification and drawings will easily understand that the subjectmatter disclosed and claimed herein could be readily implemented forother movable objects that carry cargo in a secured manner, and can alsobe readily implemented for a stationary cargo compartment or structure,such as a storage unit. Any differences in the design of the disclosedsubject matter that is relevant to a specific mode of transportation (orstationary) will be discussed herein in detail.

The system 10 is configured to define the inner walls 17 of a cargocompartment, and is configured to be fixedly assembled to the supportstructure of the cargo compartment 18 to be fixed with respect to theouter walls 12, 14 of the cargo compartment. The system 10 wheninstalled provides a smooth inner wall 17 within a cargo compartment andprovides a plurality of apertures 90 at various different positions toinstall decking beams (such as conventional A or E decking beams) orlogistics straps within the cargo compartment for supporting cargo onmultiple levels as well as for appropriately shoring cargo duringtransport. The system 10 is configured to support vertical tracks 80 forcaptive beam systems. Captive beam systems are known in the art andinclude a track 80 that receives a shoe that supports one end of adecking beam, with the opposite end of the decking beam being supportedby a second shoe that is received within a second track 80 that ispositioned on the opposite side wall of the cargo compartment 18. Theshoes are configured to be slidable within the tracks, to allow thedecking beam to be positioned at a desired height within the cargocompartment, with the shoe including a plurality of lugs or other typeof fitting that is selectively received within one of a plurality ofcorresponding apertures or lugs/nodes within the track to fix the shoe(and therefore the decking beam) in the desired position. When thedecking beams are not desired (such as during loading and unloading),the decking beams can be slid along both opposite tracks toward theceiling. In some embodiments the shoes are connected to the decking beamwith an adaptor that allows the decking beam to telescope with respectto the shoe, which allows the decking beam to be moved upward anddownward along the opposed tracks 80 one side at a time.

The system 10 is provided to receive tracks 80 for a captive beamsystem, with the front surface 82 of the vertical track 80 eitherdisposed along the same plane as the inner facing surface 48 of theinner panels 40, or in other embodiments (as shown in FIG. 5) the frontsurface 82 of the vertical track 80 is slightly recessed inwardly from aplane Q through the inner facing surface 48 of the inner panel 40, andspecifically the inner facing surface 48 of the central portion 42 ofthe inner panels 40.

The system 10 is best shown in FIG. 2. The system includes a pluralityof inner panels 40, which each span between two neighboring verticallogistics posts 32 that are attached to the outer walls 12, 14 of thecargo compartment (or in some embodiments provide the structural supportfor the outer walls 12, 14 of the cargo compartment and/or the roof ofthe cargo compartment). Many conventional cargo compartments includeinner volumes that are formed with outer walls and exposed logisticsposts 32 that provide structure for connection of cargo controlequipment as well as other components.

The inner surface of the cargo compartment 18, when the system 10 isinstalled, includes a plurality of panels 40 that are disposed along theentire length, or a portion of the entire length, of the cargocompartment 18 to form the inner walls 17 of the cargo compartment. Insome embodiments and as discussed in detail below, the panels 40 includeone or more recessed portions 52, 54, 56 vertically disposed along allor a portion of the height of the panels, which are configured toreceive vertical tracks 80 for a captive beam system. As discussedbelow, the recessed portions define voids that are spaced to allow forthe elongate tracks 80 to be positioned at consistent spacings (such ason 16 inch centers) when the panels 40 are installed, such that aplurality of captive beams can be provided within the cargo compartment18 at consistent spacings for use.

The inner wall portion, or panel 40 is best shown in FIGS. 2, 4, and 6.The panel 40 includes a central portion 42 and right and left endportions 44, 46 that are each disposed outboard of the central portion42 and on respective opposite right and left sides of the centralportion 42. The central portion 42 includes a planar front face 48through which a plane Q extends (FIGS. 4, 5). When a plurality of wallpanels 40 are installed within the cargo compartment to collectivelydefine an inner wall 17 of the cargo compartment (FIG. 1), each of thefront faces 48 of the neighboring panels 40 may extend along the sameplane Q.

The panels 40 may be sized to extend from the floor 19 of the cargocompartment to the roof 16 of the cargo compartment, or specifically theinner surface of the roof. In some embodiments, the cargo compartmentmay include structural bottom rails 11 and or top rails 11 a. In theseembodiments, the panels 40 may be sized to abut against the bottom andtop rails 11, 11 a when provided. The vertical tracks 80 provided uponthe panels 40, discussed herein, may be the same length as the height ofthe panels 40, or may be longer or shorter than the panels 40, dependentupon the desired length of travel of the captive beam (discussed above)that slides within the vertical track 80 and the desired stowed heightof the captive beam when not in use.

The central portion 42 of the panel 40 may include one, two, three, or adifferent plurality of parallel recessed portions (first, second, andthird 52, 54, 56 depicted in the figures, one of ordinary skill in theart would easily comprehend with a thorough review of the subjectspecification how to construct the central portion 42 of similar panels40 with a differing number of recessed portions) that in someembodiments extend vertically along the entire height of the panel 40 orin other embodiments, extend only partially along the height of thepanel 40. The recessed portions 52, 54, 56 each establish a void 53, 55,57, respectively, that provides room for a vertical track 80, which isconfigured to slidingly and lockable receive a shoe on an end of acaptive beam to allow the captive beam to be retained at a desiredposition along the length of the track 80 (and the panel 40). Therecessed portions may each extend in parallel to each other (and to theright and left side edges 44 a, 46 a of the panel 40, such that when thepanel 40 is fixed to the logistics posts 32 within the cargocompartment, the panels are disposed vertically 40 and the recessedportions 52, 54, 56 are disposed vertically to receive the tracks 80vertically.

In some embodiments, the recessed portions 52, 54, 56 are disposed at aconsistent spacing from each other, such that vertical tracks 80, whenselectively positioned with some or all of the recessed portions will bedisposed at consistent centerline spacing.

In one preferred example, the central portion 42 of the panel 40includes three recessed portions, a center recessed portion 52, andoutboard right and left recessed portions 54, 56. As shown in FIG. 2,the recessed portions 52, 54, 56 are aligned so that their respectivecenterlines S, T, R are also aligned in the same spacing relationshipand in parallel to each other. In some embodiments, the recessedportions 52, 54, 56 may be aligned such that neighboring recessedportions (e.g. S and T, and S and R) are each aligned at 8 inch spacingfrom each other (distance Z), such that the distance between centerlines T and R is 16 inches from each other (distance X, which is twicedistance Z). While this preferred embodiment is described with 16 inchcenters, which is standard and normally used in the United States, otherspacings, such as typical similar spacings for nations or regions thatuse the metric system can easily be employed instead of the dimensionspresented here.

The overall width of the panel 40 may be about 24 inches, andspecifically equal to 24 inches minus the thickness of the exposed frontsurface of the vertical logistics post 32 of the cargo compartment 18(for embodiments where logistics posts are placed at 24 inch centersalong the wall), for embodiments where the logistics posts are atdifferent spacing, the width (and number and spacing of the recesses)would similarly be modified consistent with this disclosure. As shown inFIG. 2 with this arrangement, a consistent 16 inch spacing (across twoneighboring panels 40, 40′ and the logistics post 32) can also be 16inches (distance X) when the track 80 is disposed within the centerrecess 52 of the second panel 40′ and the post is within the left recess56 of the first panel 40. Accordingly, in this arrangement, neighboringpanels 40 support vertical tracks 80 within differing recessed portions52, 54, 56 to maintain the consistent spacing the vertical tracks 80(one panel 40 has tracks 80 at the right and left recesses 54, 56, whilethe neighboring panel 40′ has a track 80 at the center recess 52′ and soon). This arrangement allows for the multiple of the same panel 40 paneldesign to be used to form the entire desired inner wall 17 of the cargocompartment, with the tracks 80 selectively positioned within some (butoften not all) of the recesses to achieve the desired centerlineposition of the tracks 80.

The panel 40 includes right and left end portions 44, 46 that aredisposed, respectively outboard of and connected to the central portion42. The right and left end portions 44, 46 each include a flat portion45, 47 that are configured to rest upon a logistics post 32 andspecifically a flat portion of the logistics post 32 that is outboard ofa central portion of a logistics post (which normally includes aplurality of apertures disposed therealong (which can receive ends ofconventional beams, such as A or E beams). The left and right endportions 44, 46, and in some embodiments the respective flat portions45, 47 are fixed to the logistics post 32 with a plurality of fasteners,such as screws, rivets, adhesive or the like.

In some embodiments, the central portion 42 of the panel 40 may includea plurality of apertures 90 spacing disposed therein. The apertures 90are provided to receive an end of a decking beam (such as a conventionalA or E beam), or other cargo control structure. In some embodiments, theapertures 90 may be disposed in a plurality of horizontal rows withconsistent spacing between neighboring apertures 90 in each row. In someembodiments, vertically neighboring rows may be provided such thatapertures 90 are aligned vertically along the same line, while in otherembodiments, as shown in FIGS. 2 and 6, the apertures 90 may be disposedin a staggered orientation. For example, vertical rows may bepositioned, such that a horizontal centerline S of one, some, or all ofthe apertures 90 within a row are vertically aligned with a center pointP along the wall of the central portion 42 that is midway between thehorizontal centerlines of two adjacent apertures 90 in the row below.Other patterns of apertures 90 may be provided.

In some embodiments, the panel 40 may be constructed from a single sheetof material that is formed into the desired orientation by bending, withthe bending process forming the plurality of recesses 52, 54, 56, andthe right and left end portions 44, 46. The apertures 90 in the centralportion 42 (when provided) and a plurality of apertures 104, 106 in therespective right and left end portions 44, 46 may be established bystamping or machining. In some embodiments, the panel 40 is formed bysteel, while in other embodiments, the panel 40 may be formed by othermetals, and in other embodiments, the panel 40 may be formed by acomposite or plastic, or multiple layers of materials. One of ordinaryskill in the art with a thorough review and understanding of thisdisclosure, as well as an understanding of the rated loads to besupported by the panels (though direct connection with the apertures 90,when provided), as well as the load carried by the vertical tracks, viathe captive beam system, will be able to determine the type of materialthat is best used for the panels based upon cost, availability, andweight considerations.

As best shown in FIG. 3, the panel 40, and specifically the plurality ofpanels 40 that are aligned with a plurality of logistics posts 32 toform an elongate inner wall 17, may be disposed in parallel with andclosely mounted to the respective outer wall 12, 14 of the cargocompartment 18. In some embodiments, the outer wall 12, 14 may supportthe logistics posts 32, while in other embodiments, the outer wall 12,14 may be supported by the logistics post 32. In some embodiments, thepanels 40, when positioned with respect to and fixed to the logisticsposts 32 may be disposed such that the central portion 42 of the panel40 is aligned in parallel with the outer wall 12, 14. In embodimentsdepicted in FIG. 3, the panel 40 is constructed such that the back wallof each recessed portion 52, 54, 56 is proximate to but not nominally incontact with the outer wall 12, 14. In other embodiments, as shown inthe modified detail view of FIG. 3a , the recessed portions 52, 54, 56may be constructed such that they are in contact with the outer wall 12,14.

In other embodiments depicted in FIGS. 8-9, the system 10 may bemodified to include a plurality of panels 140 that are attached tospaced logistics posts 32 within a cargo compartment 18, where thepanels 140 include a central portion 142 and right and left end portions144, 146, which contact and are fixed to neighboring logistics posts 32,such as in the manner that the end portions 44, 46 connect to logisticsposts 32 as discussed above. In these embodiments, the central portion142 is formed without elongate recesses, such that elongate tracks 180(or potentially elongate track 80 as depicted in FIGS. 1-7) can be fixedto the central portion 142 at desired spacings to establish consistentvertical centerline spacing between the elongate tracks 80. In theseembodiments, the front face 182 of the elongate track extends proud ofthe planar front face of the central portion 142 of the panel.

In some embodiments depicted in FIGS. 10-15, a modified system 1000 isprovided. The system 1000 includes a plurality of panels 1040 areprovided along the inner surface of the inner walls 17 of a cargocompartment in much the same manner as the system 10 described above.The panels 1040 used with the system 1000 are the same as the panels 40used with the system 10 with the specific differences mentioned herein.

Panels 1040, as in the panels 40, each may span between two verticalneighboring logistics posts 32 that are attached to the outer walls 12,14 of the cargo compartment (or in some embodiments provide thestructural support for the outer walls 12, 14 of the cargo compartmentand/or the roof of the cargo compartment), with the panels being fixesto the logistics posts. In other embodiments, the panels may be fixeddirectly to the trailer walls or to other structural components of thecargo compartment.

The inner surface of the cargo compartment 18, when the system 10 isinstalled, includes a plurality of panels 1040 that are disposed alongthe entire length, or a portion of the entire length, of the cargocompartment 18 to form one or both of the inner side walls 17 of thecargo compartment. In some embodiments and as discussed in detail below,the panels 1040 include one or more recessed portions 1052, 1054, 1056vertically disposed along all or a portion of the height of the panels,which are configured to receive vertical tracks 80 for a captive beamsystem, such as the panel 1040 a (FIGS. 11-12) that includes onerecessed portion 1052 and a panel 1040 b (FIGS. 13-15) that includes tworecessed portions 1054, 1056. In some embodiments, the panels 1040 maybe installed in a repeating pattern between panel pattern as in: 1040 a,1040 b, 1040 a, 1040 b etc., while in other embodiments only the panel1040 a (or 1040 b) may be used or the panels 1040 may be installed inother patterns as would be appreciated by one of ordinary skill in theart after a thorough review of this specification.

As discussed below and similar to the panels 40, the recessed portions1052, 1054, 1056 define voids that are spaced to allow for the elongatetracks 80 to be positioned at consistent spacings (such as on 16 inchcenters) when the panels 1040 are installed, such that a plurality ofcaptive beams can be provided within the cargo compartment 18 atconsistent spacings for use. As with the panel 40, the recesses in thepanels 1040 are disposed such that the front surface of the elongatetrack 80 is flush with or slightly recessed below the front surface ofthe panel 1040.

The panels 1040 (including panels 1040 a, 1040 b) include centralportions 1042 (similar to 42 as discussed above) and right and left endportions 1044, 1046 (similar to 44, 46) that are each disposed outboardof the central portion 1042 on respective opposite sides of the centralportion 1042. As with portions 44, 46 discussed above, the right andleft end portions 1044, 1046 each include a flat portion that areconfigured to rest upon a logistics post of the trailer and specificallya flat portion of the logistics post that is outboard of the logisticspost that normally includes apertures for receiving decking beams or thelike. The portions 1044, 1046 each may be made with a plurality ofpredrilled holes 1090 that are provided to allow for fasteners toconnect the panels to the logistics posts of the trailer. The predrilledholes 1090 may be provided at consistent spacings, such as 1 inchbetween centers of neighboring holes 1090.

As shown in FIG. 10, a plurality of panels 1040 (either uniform panels,or alternating panels 1040 a, 1040 b) may be disposed upon the side wallof a trailer (and fixed to the logistics posts of a trailer, or to otherstructure of the trailer) to define an inner surface of the trailer andto allow for attachment for elongate tracks 80 thereto to receivecaptive beams along the elongate tracks (as in the system 10 discussedabove). In system 1000, the panels 1040 may be arranged in a verticallystaggered manner along the length of the side wall. In one embodiment,the bottom edge 1048 of the panels 1040 neighboring the front (enclosed)end 2 of the cargo compartment (panels C of FIG. 10) may be closest tothe floor 19 of the trailer, and after a certain number of panels (suchas 1, 2, 3 or the like) that are disposed along the length of the sidewall at that height, the next certain number of panels 1040 (panels D)may be disposed vertically higher, such as 1 inch higher than the panels1040 closest to the front end of the trailer, such that the bottom edge1048 of those panels is one inch higher. Further panels 1040 may beagain vertically higher (see panels identified as E and F in FIG. 10)such as two inches higher than the panels C along the length of the sidewall of the trailer. While FIG. 10 depicts four staggered verticalheights of the panels, one of ordinary skill after a thorough review ofthis specification will easily comprehend that more or less verticalstaggers can be used during installation. This system 1000 may be usedfor trailers where the roof 6 of the trailer is not parallel with thefloor 19 of the trailer (as depicted in FIG. 10), as is sometimes usedin industry, such as to allow for a slightly bigger rear door for easeof loading and unloading cargo from the trailer. The system 1000 allowsfor the top edge 1049 of the panels 1040 to be close to the roof 6 ofthe trailer along the length of the trailer as possible, such that thecaptive beams (that travel along the elongate tracks 80) can be as closeto the roof 6 as possible when vertically stowed to allow the maximumroom within the trailer for unloading and loading.

The inclusion of holes 1090 upon the right and left portions 1044, 1046of the panels 1040 at close consistent spacings allows for the panels1040 to readily be installed upon the side wall of the trailer at thestaggered vertical heights without requiring detailed measurements bythe installed, rather the eyeball can install the panels at a desiredvertical staggering (such as with 1 inch staggering between panels C andD, and between panels D and E and so forth) by simply fastening thepanels at the same level above the floor with staggered holes upon thepanels 1040.

While particular elements, embodiments, and applications of the presentinvention have been shown and described, it is understood that thedisclosure is not limited thereto because modifications may be made bythose skilled in the art, particularly in light of the foregoingteaching.
